MEANS FOR ATTACHlNG-HANDLES TO BRUSHES.

- SPECIFICATION forming part of Letters Patent No. 655,181, dated August 7, 1900.

Application filed December 23, 1899. Serial No. 741,440. \"No model.)

To all whom, it may concern.-

Be it known that we, FRANK BAUERLE and GEORGE BAUERLE, citizens of the United States of America, and residents of Chicago,

in the county of Cook and State of Illinois, have invented certainnew and useful Improvements in Duster Heads and Handles, of which the following is a specification.

Our invention relates particularly to improved means for fastening handles to dusterheads. Its main objects are, first, to avoid the necessity of threading the heads and handles; second, to provide for using blocks for making said heads of a quality of wood which could not be used with the old method of threading, and, third, to provide for readily determining the position at which the handles maybe removed from the head. We accom plish these objects by the device shown in the accompanying drawings, in which- Figure 1 is an elevation of a duster-head, partly broken away, constructed according to our invention. Fig. 2 is avertical section of a metallic cap adapted to fit over the end 5 of the duster-head. Fig. 3 is a top plan of said cap. Fig. 4 is a front elevation of the handle, partly broken away, having a stem adapted to fit into said cap and head. Fig.

5 is a rear elevation of said handle and stem. Fig. 6 is an enlarged perspective view of said handle and stem, partly broken away. Fig. 7 is a vertical section, partly-broken away, of the duster-head when secured together.

The duster-head 1 is turned out of wood in the ordinary manner, except that the perforation 2 therein is not threaded. The stem 3 of the handle is made to fit said perforation 2 and is longitudinally slidable and turnable therein. The cap 4 is made to fit over the end 5 of the duster-head. Said cap has an aperture 6 in its lower end. The aperture 6 is made of substantially the same outline as the stem 3, said stem being circular in crosssection, except that the stem is flattened or cut away on one side, as at 7. At the base of said stem is a groove 8, extending from one side of the flattened surface 7 away from said surface toward the rear of the stem. Said groove does not extend entirely around the stem, but terminates at the back of same, so as to leave an ungrooved part 9 at the base of the stem. At the edge 10, adjoining the aperture 6 of the cap 4, is a raised part 11. The cap 4 is made of spring-steel, and the raised part 11 is designed to fit snugly in the groove 8 of the stem. The upper part of the cap is provided with perforations 12, whereby the same may be tacked to the end 5 of the duster-head. The handle 13 has a shoulder 14 at the upper part adjoining the base of the stem and immediately below the groove 8.

The operation of our device is as follows: The cap 4 is first permanently secured to the end 5 of the duster-head. The stem 3 of the handle will now be inserted through the aperture 6 and into the perforation2, the flattened surface 7 registering with the edge 10 of the cap. When the stem is entirely inserted, so that the shoulder 14 abuts the lower end of the cap, the handle will be turned toward the left. The edge 10 will now rest in the groove 8, thus preventing the withdrawal of the handle. The handle may be turned until one side of the edge reaches the solid part 9 at the rear end of the groove 8. To remove the handle, the same will be turned back to its former position and will be stopped by the solid part 9 in proper position to be withdrawn from the cap and duster-head.

It will be understood that the raised part 11 may be omitted and that other details of construction may be altered without departing from the spirit of our invention. We therefore do not confine ourselves to said details, except as hereinafter limited in the claims.

What we claim as our invention, and desire to secure by Letters Patent, is

1. The combination of a duster-head having a perforation therein; a handle having a stem fitting in said perforation; said stem being flattened or cut away on one side, and having .at its base a groove extending away from one side of said flattened surface part way around said stem and terminating at a point back of said flattened surface; and a metallic cap secured to said head, having an aperture of substantially the same outline as a cross-section of said stern above the groove, and being adapted to engage said stem at said groove, substantially as described.

2. The combination of a duster-head having a perforation therein; a handle having a stem fitting in said perforation; said stem being flattened or cut away on one side, and face, and being adapted to engage said stem having atv its base a groove extending away at said groove,substan-tially as described. from one side, of said flattened surface part Signed by us at Chicago, Illinois, this 21st way around said sitefilnfland germifnating aga day of December, 1899.
